where \(\kappa _{\rm r}\)  is the radiative opacity and \(\kappa _{\rm c}\)  is the
conductive opacity. We use the OPAL radiative opacities in our calculations.
The new tables include some new physical factors, e.g. the L-S coupling effect of
iron atoms. The conductive opacities consist of two parts which are from Itoh et
al. ([1]}, [2]}) and Hubbard & Lampe ([3]}). In the actual
calculations, we use Itoh et al. opacities only in \(\lg \rho \ge 1.8\)  region and
Hubbard & Lampe opacities in \(\lg \rho \le 1.5\)  region, in the range
of \(1.5<\lg \rho <1.8\)  linear interpolation being performed.
